This invention relates to an improved detachable point for a plow share, and one of the objects of the invention is to provide a device of ,this kind, which is simple, ecient and practical in construction, and may manufactured at a small cost and soldat a reasonable profit. H

A furtherlobject of the invention .is to provide a device of this kind cbmprising improved features of construction, one of which consists in the provision of a pocket formed in the detachable point, for the re-- ception of the end of a plow share, in combination with a lugcarried integrally by one wall of the pocket' and engaging adjacent the share landside of the plow share and being secured thereto, thereby holding the pocketed point to the. share. VIn practical fields the details of construe tion may necessitate alterations falling with The invention comprises further features and combination of parts as hereinafter set forth shown in the drawings and claimed.

In the drawings Figure 1 is a view in perspective of the to a share.

Fig. 2 is a perspective view of a portion of the share showing its opposite sides, and

Referring more especially to the drawings, 1 designates a portion of a share' and 2 denotes a share landside. The share and the ,share landside flange 2 are at acute angles, and adjacent where the share merges into a curved forward edge 3, said share is V- shapedin cross section.

from the forward curved edge 3, the share landside angc 2 terminates into a. shoulder 4, The point 5 is provided with a forward cutting edge 6, and cutting` edge 7. This detachable point 5 is constructed from a single piece of metal, bent upon itself, and where the bend is made, the folded parts are welded together and drawn to the shape shown clearly in Figs. 1, 2 and 5, and constructed with said cuttingI edges 6 and 7. Onelside of the point overlaps the outer face .of the share 1 which has anupper cutting edge 8, which merges into the upper cutting edge 7, as shown clearly`in Fig. 1. Between the two sides 9 and 10 of the detachable plow point a pocket 11is formed, for the reception of the end part 3 of the share. The side 10 of the detachable point has an integral extension lug 12 provided with a slot 13 for the reception of the bolt 14, which passes throh' the share, therebeing a nut 15 threaded on the bolt for drawing the washer 16 tight against the extension lug 12. The side 10 of the point has a shoulder 17 to engage the shoulder 4 of the landside 2.

` The extension lug 12 has-its under edge overlying the landside as shown clearly in Fig. 2. By means of the disposition of the extension lug 12, the inter-engaging shoulders 4 and 17, and the` engaging curves of the pocket and the end 3, the detachable point is held against displacement during its passage through the soil. By removing the bolt 14 the point may be detached and sharpened and replaced, or a new point substituted.

The invention having been set forth what is claimed as new and useful iszl. The combination with a share having a forward curved end portion, of a point constructed from a single piece of metal bent on itself and welded and drawn to a point and provided with a pocket between the folded parts, the inner end of said pocket being curved and engaged by the forward curved portion of the share, one side of the pocket 100 having an extension lug 'engaging the rear face of the share and overlying the share landside, one side of the pocket and the share landside having inter-engaging shoulders and means passing through the exten- 105 and tapered, of a point constructed from a 110 single piece of metal bent upon itself 'subsequently welded and drawn to a point hr ving a cutting edge and provided between the folded parts with a pocket curved longitudinally and tapered correspondingly `to and receiving the forward longitudinally curved end portion of the share, the share landside having a shoulder, one of the folded parts of the point having a shoulder abutting the shoulder of the sharelandside, and also provided with an extension lug engaging the rear face of the share and overlying the share landside, said lug having an elongated slot, and means passing through the share and through the slot and provided with a securing device for clamping the parts t0- gether, said share landside extending at a slight acute angle to the rear face of the share and coperating with the lug, whereby excessive tension is relieved on the securing device.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
